Nothing good that I'm aware of.

One could make an alias for the various compilers which first sets a
suitable GCC_EXEC_PREFIX, calls the desired compiler, then unsets
GCC_EXEC_PREFIX or something like that.

Another approach is to use the -B argument to the compiler, which (effectively)
allows you to specify a prefix on the command line.
